[Improvement Case] Chain Breakage of Conveying Conveyor - Kaizen
Makome Research Institute MACOME CORPORATION
Frequent cutting troubles with the chains used for the conveyor for transportation. A case where a line downtime of zero was achieved.
We would like to introduce a case where we improved the chain breakage of a conveyor system. At a wood processing manufacturer, troubles with the conveyor frequently occurred. The workpieces were very heavy, leading to breakage of the top chain and resulting in loss due to downtime. There was a request to monitor the lifespan of the chain. We installed a magnetic proximity switch "DW-350" under the conveyor and attached a magnetic body "SMG-100N." This allowed for management of the top chain count, enabling a shift from reactive maintenance to preventive maintenance. [Challenges] - The conveyor's top chain reaches material lifespan at 1,650 rotations, so we want to replace it before that. - We want to shift from "reactive maintenance" to "preventive maintenance." - Since it involves wood processing work, photoelectric sensors cannot be used due to dust interference. - We need a sensor that can reliably count to ensure wear is accurately tracked up to 1,650 rotations. *For more details, please refer to the related links or feel free to contact us.

basic information
**Points of Kaizen and Expected Customer Benefits** - The DW-350 is a non-contact type that can detect up to a distance of 40mm. - A magnet is installed upside down on the top chain, allowing for 2-channel output to reliably count rotations. - Although a work stop limit switch was previously used, the DW-350 can also serve as a replacement for the limit switch. - The DW-350 is equipped with a "saturable coil" magnetic detection element, which has high directionality and can detect magnetic fields from both N and S poles, making it usable even in areas with significant impact. *For more details, please refer to the related links or feel free to contact us.*
